WRENCH.

SPECIFICATION forming part of Letters Patent No. 762,537', dated June 14, 1904:.

Application filed october 19, 190s.

T fir/ZZ Ill/1,071 717; 7??,/1/7/ concern:

Be it known that I, LEo KULEs, a citizen of the United States, residing at South Lorain, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Wrenches; and I do hereby declare the following to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to the iigures of reference marked thereon, which forms a part of this specification.

This invention relates particularly to that class of monkey-wrenches in which the movable jaw is actuated by a screw having right and left threads, one of which engages with the handle or lixed part of the wrench and the other of which engages with the said jaw.

rEhe object of the invention is to improve the construction of such wrenches by providing more convenient means for the manipulation of the jaw and by providing an improved construction of screw with respect to its bearings upon the other parts of the wrench.

r1`he accompanying drawing is a longitudinal sectional view of the wrench.

Referring speeiiically to the drawing, 6 indicates the iiXed jaw, on the shank 7 of which the movable jaw 8 is slidable.

9 indicates a spindle having right and left threaded portions 10 and 11, the latter of which takes in threads produced in a recess or hollow 12 within the movable jaw. The

spindle is mounted in bearings in a housing Serial No. 177,615. (No model.)

13, attached to the shank and forming part of the handle of the wrench.

The threads 10 engage corresponding threads 10, formed in the end of the housing nearest the movable jaw. The spindle extends lengthwise through the housing and out beyond the foot of the wrench, where it has a nurled head 14, whereby it may be turned. The location of the nurled head at this point makes it more convenient to manipulate the wrench, especially in tight quarters, than it' located under the shank, as usual.

rIhe quick action produced by the opposite threads is obvious, and the handle construetion gives a fair hold and covers and protects the screw adjustment. I am aware that 1t is not broadly new to use an oppositely-threadcd screw to move one jaw of a wrench, and this I do not claim; but

I/VhatI do claim, and desire to secure by'Letters Patent, is-

In a wrench, the combination with a fixed jaw and shank, of a movable jaw slidable on the shank, a handle-housing on the shank and threaded internally, and a spindle, having right and left threads engaging respectively in the housing and movableg jaw, extending through the housing and having a finger-piece thereon at the foot of the wrench.

In testimony whereof I aiIiX my signature in presence of two witnesses.

LEO KULES.
